sieve script is not exescuted

I have scripts in 2 places: sieve_script personal { path = ~/.dovecot.sieve }

sieve_script before { path = /etc/dovecot/sieve }

/etc/dovecot/sieve is directory with (currently) one script. This script add header to message.

And it seems, that "before" script is not executed. Any hints? KJ
